ABSTRACT: This paper depicts the design of NAND gate for nanotechnology. The basic elements which are used in the sketch is Carbon Nanotubes instead of the conventional silicon-based units. The special properties of the carbon nanotubes such as high thermal conductivity & electrical conductivity, aspect ratio, very elastic, high flexibility, high tensile strength, low thermal expansion coefficient and highly flexible which means can be bent considerably without damage. In addition to these basic properties, the Carbon nanotubes give a special opportunity of scaling the circuit design to the nano regime. The logic gate which is designed with the help of CNFETs and CVSL proved to be such an achievement that can ahead used to make complex circuits. The circuit proposed of the logic gate in this paper is designed using the 32nanometre Stanford units CNFET technology and is compared with the conventional.........

ABSTRACT: Electronic circuits are exposed to very high energy radiation in the harsh conditions of outer space. This leads to soft errors such as single-event upsets (SEU), double-event upsets (DEU) and single-event transients (SET). The memory circuits are the most susceptible to these soft errors resulting in severe data loss. This paper proposes the design for an SRAM cell that is radiation hardened by design (RHBD). A comparative study of the standard SRAM cell and the RHBD SRAM cell indicates that the proposed design is resilient to SEUs and DEUs. The proposed design is an improvement on the 8T SRAM cell design and includes a 20T triple interlocked cell (TICE) design. The error correction capabilities of both designs are compared by manually injecting bit upsets at crucial nodes in the circuit. It is observed that the TICE design provides a 96.75% and 98.5% improvement over.........
